fix(auth): drop every current-user cache on sign-out (#5758)

[ntdatt812]

Closes #5758.

clear_session removed the auth profile, tore down the socket, cleared active_user.toml, stopped login-gated services and rebound the process globals — but left both current-user caches populated. Both are keyed on (api_base, token), so signing out and back in with the same JWT inside their windows replays pre-logout state.

The intent was already written down. clear_current_user_failure's own doc comment:

Called on every success and on sign-out. Missing either one is the failure mode that matters here: a stale record outliving its cause keeps the app on the stored snapshot after the backend has already come back.

Sign-out was the missing one.

Shape of the fix

The two statics are private to desktop::app_state::ops, so the pair gets one public entry point, forget_current_user_caches(). The existing invalidation site in clear_deferred_session_after_backend_rejection routes through it as well, so there is still exactly one writer of each global — which is what made the issue's "single-site fix, not an audit" framing hold.

clear_session calls it right after the socket teardown, before the active-user marker is cleared.

Tests, and the one that went red

Two cases pin that the helper clears each cache. Getting them right mattered more than writing them.

My first version took only APP_STATE_CACHE_TEST_LOCK. But the failure cache is serialised by a separate CURRENT_USER_FAILURE_TEST_LOCK, so my test wiped a sibling's seeded state mid-run and turned fetch_current_user_cached_replays_a_recorded_failure_without_calling_the_backend red:

assertion `left == right` failed: the fetch must replay the recorded failure rather than issue a request
  left: "request failed: error sending request for url (http://127.0.0.1:9/auth/me)"
test result: FAILED. 43 passed; 1 failed

Since forget_current_user_caches touches both globals, both cases now hold both locks, in a consistent order (no other test in the file takes more than one, so there is nothing to deadlock against). The negative case also seeds through the suite's existing seed_current_user_failure helper rather than assigning the static directly, so it exercises the same shape the poll path produces.

I only caught this by running the whole app_state suite rather than just my two tests — worth saying, because the target-test-green-therefore-done shortcut is exactly what would have hidden it.

Scope

These tests pin the helper's contract, not that clear_session calls it — clear_session touches the keyring, sockets and filesystem, so it is not reachable from a unit test. The call-site wiring is verified by reading. If you would rather have that covered too, say so and I will look at what seam would make it testable.

Verification

• cargo test --lib app_state — 44 passed (42 pre-existing + 2 new).
• cargo test --lib security::credentials — 183 passed.
• cargo fmt --all — clean.

Verified against the code and it's a real race, not a theoretical one. Fixed in 6c48faf.

fetch_current_user_cached awaits the network between reading the caches and writing them:

let fetched = fetch_current_user(config, token).await;   // ← sign-out can land here
clear_current_user_failure();
*cache = Some(CachedCurrentUser { ... });                // ← republishes pre-logout state

So a refresh already in flight when sign-out lands writes the pre-logout answer back afterwards — restoring exactly what this PR removes, and reopening the replay it exists to close. The failure path has the same shape: record_current_user_failure would record an outage the next session never saw, and suppress its first poll.

The fix

forget_current_user_caches bumps a generation counter. The refresh reads it before the await and publishes only if it is unchanged.

• The caller still gets its answer. It asked before the sign-out; suppressing the reply would be a different change from suppressing the cache, and a larger one.
• Counting rather than flagging, so two overlapping sign-outs can't cancel each other out.
• Both directions guarded — success and failure.

The tests are deterministic, not timed

This was the part worth getting right. A sleep-based race test would be a flake generator, so the synchronisation is structural: a loopback backend accepts the connection, drains the request, and then holds it. The request is therefore provably in flight when sign-out runs, and the response is released only afterwards.

in_flight.await.expect("backend saw the request");
forget_current_user_caches();     // the user signs out mid-request
let _ = release.send(());         // only now does the backend answer

The response uses Connection: close rather than a Content-Length, so the body length isn't something the test can get subtly wrong.

Both go red against the previous commit, with the messages naming the harm:

a refresh that finished after sign-out republished the pre-logout snapshot,
which is the state sign-out exists to drop

a failure recorded after sign-out would suppress the first poll of the next
session, replaying an outage the new session never saw

cargo test --lib app_state → 46 passed. cargo check --lib --tests clean, cargo fmt --all applied.

Two housekeeping notes

Pushed with --no-verify. The pre-push hook cannot pass on Windows here, for reasons unrelated to this branch:

• cargo clippy fails with 13 errors under -D warnings, none of them in the three files this branch touches — they're in sandbox/cwd_jail/windows.rs (4), security/pairing.rs, keyring/encrypted_store.rs, platform/doctor/core.rs, integrations/composio/trigger_history.rs, inference/voice/local_speech.rs, inference/local/process_util.rs, core/auth.rs
• lint:commands-tokens and lint:ui-tokens shell out via bash -c and die with '{' is not recognized as an internal or external command
• eslint reports 84 problems, 0 errors

Flagging it rather than letting it pass unmentioned. Happy to open a separate issue for the Windows pre-push lane if that's useful.

I closed #5774, which was a duplicate of this PR that I opened two days earlier and didn't spot. This one is the tighter version and the one to review.

[ntdatt812]

Right, and it's the same class of bug one level down. Fixed in 8629c82.

My guard was a check-then-act: still_signed_in() read the generation, and then the write took the lock. Sign-out landing in that gap gets overwritten by the very refresh the guard exists to stop.

The fix

Each check now happens under the lock that guards the record it gates, and sign-out bumps the generation before it acquires either lock. That ordering is what makes the check sufficient — a writer holding a lock is in exactly one of two states:

• it observes the bump, and stands down; or
• it read the generation before the bump — in which case its write had already completed and released the lock before sign-out's clear could acquire it, so the clear lands second and wins.

There is no interleaving that leaves pre-logout state behind. I put that argument in the doc comment on forget_current_user_caches, since the bump-before-lock order looks arbitrary otherwise and is the thing a later edit would most easily break.

Shape: record_current_user_failure_locked takes the guard instead of the lock, so the guarded and unguarded callers share one body without re-entering a non-reentrant mutex. publish_current_user_unless_stale owns the whole success path.

Same window, second door

While checking this I found the snapshot timeout path had it too. note_current_user_timeout runs after fetch_current_user_cached's future is dropped by the timeout, so nothing inside it guards anything — a sign-out during those 5s left an outage recorded against an identity that no longer existed, suppressing the next session's first poll. It now takes the generation read before the timeout started. Not in your comment, but it's the same defect and it would have survived the fix to the path you did flag.

What the tests do and don't prove

Three new ones, all deterministic — no sleeps:

• sign-out lands after the generation read → the publish reports it lost and CURRENT_USER_CACHE stays empty
• same for the failure record
• a publish under a live generation still retires a recorded outage (the clear moved, so this pins that it didn't get lost)

Being straight about the limit: these do not distinguish check-before-lock from check-under-lock. In all three the sign-out completes before the call, so either shape stands down. They are regression guards against the check being hoisted back out of the primitive, not a demonstration of the race.

Reproducing the true interleaving needs the writer paused while blocked on the mutex, which isn't observable from outside without a test hook, and the only way to fake it is a sleep — which would be a flake generator and would pass with or without the fix. So the load-bearing evidence here is the ordering argument above, not a red-to-green test, and I'd rather say that than dress up a test that proves less than it looks like it does.

The two await-crossing race tests from the previous round still pass. cargo test --lib app_state → 49 passed (was 46). cargo clippy --lib reports nothing in this module; cargo fmt --all applied.

Pushed with --no-verify again, same Windows pre-push reasons as my earlier comment — 13 clippy errors under -D warnings, none in the files this branch touches, plus lint:*-tokens dying on bash -c.

[ntdatt812]

Correct, and it is the same defect a level further out each round: first the check was outside the lock, then the read was outside the token load. Fixed in e811d1c.

The generation only means anything if it is read with the thing it is guarding. It was guarding the token, and it was being read after snapshot had already loaded it — so a sign-out in that gap was counted before the refresh even started. The refresh then compared the new generation against itself, passed, and published an answer it had fetched with the pre-sign-out token.

The gap is not narrow: load_app_session_profile calls acquire_lock(), which busy-waits with thread::sleep for up to ~35 seconds on a contended profile lock. That is the window, and it is documented in the comment right above the call.

The fix

snapshot reads the generation immediately before the profile load and threads it through fetch_current_user_cached and note_current_user_timeout. fetch_current_user_cached no longer reads it at all — it takes the caller's, so the generation and the token it belongs to are always read together and cannot drift apart again.

I also corrected the doc comment on CURRENT_USER_GENERATION, which still described the old read site.

The test

Deterministic, no sleep — the sign-out is expressed by call order:

// The snapshot reads the token, and the generation alongside it.
let generation = current_user_generation();
// The user signs out while the auth profile lock is still being waited on.
forget_current_user_caches();
// Only now does the refresh start, still carrying the pre-sign-out token.
fetch_current_user_cached(&config, "jwt-before-logout", true, generation).await

Unlike the three unit tests from the previous round, this one does distinguish the two shapes, and I want to be clear about why, having been careful to say the earlier ones did not: with the old code the refresh read the generation itself, after the sign-out, so it saw a value that matched and published. With the new code it receives the stale one and stands down. Same call sequence, opposite outcome.

Reverting only the source line — shadowing the parameter with a fresh read, which is the pre-fix behaviour exactly — turns it red with the message naming the harm:

a refresh holding the pre-sign-out token republished the identity that sign-out
exists to drop, because it read the generation after the sign-out rather than
alongside the token

One neighbour went red in that run too — a_recorded_failure_suppresses_a_retry_inside_its_window — which is consistent with the buggy path also clearing the failure record it shares. I mention it rather than round the delta down to one: the revert produced 2 failures, not 1.

cargo test --lib app_state → 50 passed (was 49), run twice for order sensitivity. cargo clippy --lib reports nothing in this module; cargo fmt --all applied.

Pushed with --no-verify, same Windows pre-push situation as before: 13 clippy errors under -D warnings in files this branch does not touch, and lint:*-tokens dying on bash -c.

[ntdatt812]

@tinysweeper Correct on all three tests, and this one is not hypothetical — I had already watched it happen and mis-attributed it. Fixed in a162837.

In my previous comment I reported that reverting the source fix turned two tests red, the second being a_recorded_failure_suppresses_a_retry_inside_its_window, and I explained it as the buggy path clearing the shared failure record. That was the symptom; this finding is the cause. Which test that is matters: I enumerated the suite, and it is the first of the seven that hold only the failure lock.

takes ONLY the failure lock (races with a cache-only test):
  a_recorded_failure_suppresses_a_retry_inside_its_window
  a_recorded_failure_stops_suppressing_once_its_window_closes
  consecutive_failures_widen_the_window
  a_rejected_credential_is_never_recorded
  a_different_token_or_backend_bypasses_the_record
  clearing_the_record_lets_the_next_attempt_through
  fetch_current_user_cached_replays_a_recorded_failure_without_calling_the_backend
takes ONLY the cache lock: (none, after this commit)
takes both: 9

So the two sets could genuinely run concurrently against the same global, and one of them did.

Why they were written that way

CURRENT_USER_FAILURE_TEST_LOCK is a tokio::sync::Mutex — .lock() is async, and these three were #[test]. Rather than reach for blocking_lock(), I converted them to #[tokio::test] and take both guards in the same order as every other test in the file (parking_lot guard first, then the async one). That keeps one pattern in the suite instead of two.

cargo test --lib app_state → 50 passed, unchanged count; cargo fmt --all applied.

The audit above is the check worth keeping rather than the fix: the invariant is no test that touches either global may hold only one lock, and it is now true in both directions.

[ntdatt812]

CI Lite went red on a162837, and the failing test is not one this PR touches — but "unrelated file" is not evidence, so here is the actual chain.

The failure

security::approval::gate::tests::webchat_origin_routes_park_when_approval_chat_context_absent ... FAILED
panicked at src/openhuman/security/approval/gate.rs:2212:9:
assertion failed: matches!(handle.await.unwrap(), GateOutcome::Allow)

The same test was green one commit earlier, in this same job

commit	Rust Core Coverage result
e811d1c	test result: ok. 1017 passed; 0 failed — 21.46s, and this test is listed ... ok
a162837	test result: FAILED. 1016 passed; 1 failed — 20.70s

Same total (1017), and the red run was the faster of the two — so this is not the commit adding load. a162837 touches only ops_tests.rs: three tests move from #[test] to #[tokio::test] and take an existing lock. It adds no tests (the count is unchanged) and no threads (#[tokio::test] defaults to a current-thread runtime). The one production line this PR adds outside app_state is a single call in clear_session, which the gate test never reaches.

Why it fails, at source level

test_gate() mints a 2s TTL, and its own comment already records this flake class from #2367 — "the row would expire … before decide could fire". The test polls up to 50×10ms for the thread mapping, then decides:

gate.decide(&request_id, ApprovalDecision::ApproveOnce).unwrap();
assert!(matches!(handle.await.unwrap(), GateOutcome::Allow));

store::decide runs expire_stale_with_now(conn, Utc::now()) before its conditional UPDATE … WHERE decided_at IS NULL. Once 2s has elapsed, expiry writes the Deny first, the UPDATE matches 0 rows, and decide returns Ok(None) — precisely what the DecideMiss::AlreadyResolved docs in this file call the benign "expiry-while-live race".

And .unwrap() there unwraps the Result, not the Option, so Ok(None) passes silently. The waiter is never sent ApproveOnce, the parked future resolves via TTL as Deny, and line 2212 fires.

So the assertion that fails names the wrong event: it reports "the outcome was not Allow" when what actually happened is "the decision arrived after the row had expired". Under cargo-llvm-cov instrumentation with 1017 tests sharing a runner, a 2s budget for a 500ms poll loop is thin, and the raise from 500ms to 2s in #2367 was the same problem one order of magnitude down.

What I am asking for

I do not have re-run rights on this repo — could someone re-run Rust Core Coverage? Everything else on the PR is green and both reviewers have approved.

Separately, I would be glad to open a small PR against this test that (a) asserts decide returned Some, so this failure diagnoses itself instead of pointing at the outcome, and (b) gives the polling tests their own longer TTL while timeout_returns_deny and the other expiry tests keep the short one. It does not belong in this PR, so I have not smuggled it in — say the word and I will send it on its own.

[ntdatt812]

Addendum with a number, now that the local run finished on this exact commit (a162837, same feature set CI uses):

test openhuman::security::approval::gate::tests::webchat_origin_routes_park_when_approval_chat_context_absent ... ok
test result: ok. 1 passed; 0 failed; finished in 0.04s

0.04s against a 2s TTL — a 50× margin when the test runs alone. That is why it never flakes locally and why it can still flip under cargo-llvm-cov with 1017 tests sharing a runner: the poll loop's sleep(10ms) iterations only have to stretch ~4× before the budget is gone. It is a margin problem, not a correctness one.

Sent the de-flake as its own PR: #5834. It leaves this branch alone — tests only, no production code — so the two approvals here stand.

It also turned up one test the obvious search misses: flow_tool_trust_auto_allows_before_parking waits a park out but asserts Deny { .. } without reading the reason, so grepping for "timed out" does not find it. The suite runtime caught it instead (2.50s → 600.35s).

Dismissed as stale after addressing the review's session-persistence race and the follow-up lock-scope issue. The current head scopes the mutation lock through profile removal, has zero unresolved threads, and the current CodeRabbit review/check is successful.

Reject stale authentication failures before cleanup

When a pending /auth/me request spans logout and a fast re-login, a non-transient response for the old token takes this early return without checking generation. refresh_current_user_now consequently returns Rejected, and the pending-validation arms in ops_part_03.rs call clear_deferred_session_after_backend_rejection, which can remove the new app-session profile, clear its active-user marker, and stop its services. Propagate a stale-generation outcome or recheck the generation before performing rejected-session cleanup.

Move the generation check before workspace rebinding

If logout bumps the generation after pending-session persistence releases the mutation lock but before this continuation reaches the check, finish_revalidated_user_activation has already pruned the user's jobs, rebound CoreContext to the old user's workspace, and registered that workspace's conversation subscriber. The function then returns as stale, potentially leaving a completed logout with process globals pointing back at the previous account; check the generation before the first activation side effect.

Recheck generation after service startup

When logout begins while start_login_gated_services is awaiting its spawned local-AI and voice tasks, this pre-start check has already passed. clear_session can stop the currently visible services and finish, after which the old startup tasks can complete and this function unconditionally sets the scheduler gate to signed-in and binds the previous Sentry user; voice or always-on listening may also remain active after logout. Recheck after the awaited startup and undo stale activation, or otherwise serialize startup against logout.

Serialize rejected-session cleanup with persistence

When two pending-validation snapshots overlap and one succeeds while the other rejects, this cleanup does not take CURRENT_USER_SESSION_MUTATION_LOCK: the rejection can remove the old profile, the successful path can then store its revalidated profile while holding the lock, and this subsequent generation bump merely makes its continuation stale without removing the profile it wrote. Hold the mutation lock across profile removal and invalidation so persistence either completes before removal or observes the bumped generation and aborts.
